a) Find the initial population. b) Find the population after 1 hour. c) How long will it take the population to double?
Solution:
a) The initial population is the population when t=0. In other words, find
b) Since the population of bacteria is measured over time interval given in minutes, the first step is to realize that 1 hour means t=60 minutes.
c) How long will it take the population to double? Let B(t) = Twice the initial population
